36 Claims.

fls'i'his invention relates to a machine for filleting An object of the invention is to provide a fishfilleting machine having novel and improved details of construction and features of operation. Another object is to provide a machine of the above type which is capable of cutting and removing the fillets, regardless of minor variations in fish sizes.

Another object-is to provide a machine of the above type having novel and improved means above type which is capable of cutting and removing fillets with a minimum amount of waste.

Various other objects and advantages will become apparent as the nature of the invention is more fully disclosed.

Although the novel features which are-believed the arrangement of the swivel guide and tail guide;

Figures 12 and 13 are detail views of the swivel guide and supporting mechanism therefor, the

In fllleting machines of the type to which the present invention relates, a decapitated and gutted fish is fed, preferably at high velocity,

tail first and back downward, between upper and lower pairs of cutting knives which are adapted :to make incisions on opposite sides of the backbone of the fish and which extend upwardly and downwardly but do not quite meet at the backbone.

Suitable feed means is provided for feeding the fish in the proper position to the cutting knives. Such a feed means may include a feed trough, centering trough, and tilting trough arranged inseries and in alignment so that the fish is progressively fed therethrough, as set forth more in detail inthe copending application of William H. Hunt, Serial No. 427,549, filed January 21, 1942, now U. S. Patent No. 2,325,680. The troughs, as set forth in that application, are adapted to position and center the fish so that the tail feather and fins pass between the pairs of cutting knives and thereby accurately.

guide the fish and prevent a cross-cut from being made which would destroy the fillet.
